M93R Semi Auto Problem

I just bought a KWA M93R NS2 version, it was working great for a while and I was able to use it quite a bit before this problem came up, but I am having an issue where burst and full auto work fine but semi just shoots full auto. I could fix it given the cause of the problem but I am not sure and i don't want to take apart a gun with so many parts w/o knowing what im looking for. I might be able to send it in for repair but i want to know how to fix this after the warranty is up, I don't want to be missing my new gun for a month, and I just spent my money paying for the gun so I cant ship if for a bit.

I NEVER abused this gun, I maintained it well kept it lubed, never dropped it, and properly stored it so I am thinking some spring is not tensioned right or got worked out of place

KWA does make great guns but I wonder how this problem never got caught during testing!

if someone could give instructions for a proper breakdown so if I do take it apart I don't mess anything up that would be great

P.S. after this problem occurred I did a field disassembly and completely cleaned every part I could access with out tearing down into the trigger assembly (where the problem most likely is)

Hop on the Help Desk at the link above to submit a repair ticket, this is not something that you can fix or be shown how to fix on your own. Our Service Center techs will need to do the modification.

These are all tested before they are shipped out, and like you said, it was working great at first. It was working great when tested at the factory and here before being shipped out to the retail stores.

We will get it taken care of for you and get it back as quickly as we can.

Alright, and what I ment w/ the testing thing was like after design during like a stress test but i will do my best to get this in as fast as i can because it is a great gun

but like u said there was not a way to detect before shipping and im sure they vary ever so slightly with each gun.
Is there anything to do to avoid this problem in the future or is it a random occurrence?

I too had the same problem this morning. My gun fired 3 round bursts on all selector switch positions. (this is a problem for me since I play in a semi only field)
I treat this thing like a little baby since I love the gun so much. I cleaned it out after the 3rd/4th use because it was locking up. I attributed that to worn out paint and dirt as the locking was fixed after I cleaned it. To date this is the 6th time I've used it. And like The OP said I have not in any way abuse this gun or dropped it in a game.
I understand that we need to send this to KWA for repair. But I would also like an explanation of the nature of the problem as this would help us owners avoid this problem in the future.

P.S.S. this gun was purchased from AirsoftGI

I had a same problem. The source (in my case, but it was the very same as yours, gun shot in burst, and in auto, only semi was out)is worn out part of burst assembly. On the diagram in the Pro shop(I lost my manual, so it must suffice) it is part 594. It is pushed down by the moving slide, and the friction of the slide wears this part down. In semi auto mode, the prong of the part 600 pushes the trigger bar (part 553) down, thus dissengaging the hamer assembly and stopping the hammer from falling again when the slide is back in the forward position. It can be home repaired(I did so), but it is only a temporary solution. I suggest replacing part 594. I believe the factory tests did not catch it because it can occur only after many, many thousands of BB's fired, and is partially efect of sand and other impurities grinding the part 594 down. Only minimal damage is needed for the problem to occur.

How much does it cost to send it in? And is this problem just going to keep occurring? I have the same problem by the way, seems like every owner of this gun has this problem as well. Its such a great gun, other than this problem, when semi auto worked, it was nearly perfect.

Just for clarification, any product that goes through our service center does receive a 5 point inspection. It is not allowed to leave our service center unless the gun is capable of operating at our factory standards. We don't just put a band-aid on the problem, we will repair it 100% and if there are any updates on that model, the item will also get updated as well. It will also receive a brand new 45 day warranty upon the item's return to you, the owner. We want to make sure that our customers are happy and satisfied!

I will! If I can ever get around to it.............Looks like we'll be backed up for at least 2 weeks if not more.....Ugggh. I had thought about inlaying some anti-friction material into the slide where that part rides & also machining a new part out of better material that contacts the slide. I determined (like you) the fastest, easiest, cheapest & user installable way to get the gun up and running was to redo part #61. BTW, After taking a better look at it I believe it's MIM - Metal Injection Molded not stamped as I previosly stated.
